The UIP(update in progress) is set when RTC is updating. We only
consider the normal oscillator(32Khz) mode.
When time base is 32kHz, the update cycle takes 1984us at the end
of every second. And the update cycle begins 244us later after UIP
is set. So the UIP is set in 2228us at end of every second.
